It is do-able. Will let you draw your own conclusions about brightness and whether or not it is compromised. Unless you've got a super-duper camera, lit blades by picture or video tend to lack a little accuracy to what you actually see in person.
Your primary Led colour makes the difference that either promotes a boosted-effect or creates an alternate blade colour with a different core. It's debatable whether this short-sells the overall effect or not.
Lord Callous did a Review a little while back with his
Bane, a 12+RED with a red Day Blade.
There's also a video demonstrating the results of different coloured Day Blades where the Primary Led colour is Blue. There's two parts, see can see
Part 1 as an indication and provides an example of what I mean by different core. An Accolyte and a Rebel are used for the demonstration.
An interesting experiment.
